4.1.1 Considerations for setting up a wireless network
When designing networks for several access points, first determine where
the access points will be positioned and how far apart they will be from each
another. To ensure that the infrastructure of your wireless cells is free of
gaps, use a mobile computer and the
AirLancer Client Manager to test the
wireless connections within the planned range. Use this method to measure
the maximum distance between the individual access points. Wireless gaps
between access points are irrelevant where no workstations are planned or
network access does not have to be guaranteed.
Each access point spans its own wireless cell using a specific channel. In
most countries there are 13 available radiofrequencies, some of which
however overlap. The actual number of channels on the ISM frequency band
that do not overlap are a maximum of three (e.g. channels 1, 6 and 13). This
means that no more than three access points within reach of a wireless LAN
can be operated completely free of interference; i.e. only three access points
per room or floor. A frequency or neighboring channel, naturally, can be used
again by other stations outside of the range.
When analyzing the network environment, the Site Monitor and Link Test
tools of the AirLancer Client Manager are very useful.
Refer to the appendix in this manual for a detailed list of frequency bands for
the individual channels.
4.1.2 Ad hoc network (peer-to-peer)
Define the direct connection between several computers in the configuration
profile using the
AirLancer Client Manager .
햲
Select the Add/Edit Configuration Profile command in the 'Action'
menu.
햳
Select and label one of the four profiles and specify 'Peer-to-peer group'
in the drop-down menu.
햴
Click Edit Profile and enter the name of the network. This name has to
be the same for all computers on the network.
You have now established the wireless bridge. You now have to set up a
network in order to access other computers.
